Title: Aromatic dinitro compound, aromatic diamino compound and their production
Inventor: MATSUO MITSUKI
IPC: C07C213/02
Filed: 1992-04-07
Abstract: PURPOSE:To obtain an aromatic dinitro compound and an aromatic diamino compound having new trifluoromethyl and biphenyl structure usable as a starting raw material for polyimide, polyamide, polyamide-imide, bismaleimide and epoxy resins. CONSTITUTION:4,4'-Bis(3-nitro-5-trifluoromethylphenyloxy)biphenyl of formula I and 4,4'-bis(3-amino-5-trifluoromethylphenyloxy)biphenyl of formula II. The aromatic dinitro compound of formula I is obtained by condensing 3,5- dinitrobenzotrifluoride with biphenol in the presence of a base in an aprotic polar solvent. The aromatic diamino compound of formula II is obtained by reducing the new aromatic dinitro compound of formula I. The compounds of formula I and formula II are useful as a raw material for polyimides having low dielectric characteristics and excellent moldability and processability.

Title: Phase detector of synchronous detection type
Inventor: SHINOZAKI NOBUHIKO
IPC: G01R25/00
Filed: 1978-07-12
Abstract: PURPOSE: To improve the degree of freedom of circuit design and to simplify the circuit by using a bistable semiconductor element with a gate having a high input impedance thereby to produce a circuit.  
     CONSTITUTION: The output of a transformer T 1  is subjected to the waveform shaping process at Sc, and bistable semiconductor elements B 1  and B 2  with gates are connected between a transformer T 2  and an integrating circuit IN so that the gates of the elements B 1  and B 2  are controlled by the output of the circuit SC. If voltages e 1  and e 2  are impressed upon the transformers T 1  and T 2  of the circuit described in the above, the element B 1  is turned on by the positive half wave of the voltage e 1  so that a current i 21  flows through the element B 1 . However, if the  element B 2  is turned off, a current i 22  does not flow. As a result, the composed current i 2  becomes the DC current in the same direction as the current i 21 . With the negative half wave, on the contrary, the opposite operations to the above are effected so that composed current i 2  becomes the positive DC current. If, therefore, the current i 2  is integrated over one cycle, a DC output V d  is obtained, from which the phase difference can be determined. Thus, the circuit can be simplified.

Title: Instantaneous voltage drop compensator
Inventor: MUKAI SHIRO
IPC: H02H7/122
Filed: 1989-04-03
Abstract: PURPOSE:To prevent erroneous function of overcurrent protective function reliably by turning a thyristor switch OFF, upon occurrence of instantaneous voltage drop, and driving an inverter thereby compensating voltage reliably. CONSTITUTION:Upon occurrence of instantaneous voltage drop of power source 1, an ON signal is outputted from an inverter control means to an inverter 5 thus driving the inverter 5 and turning a thyristor switch 3 OFF. If overcurrent flows through the inverter 5 due to some cause, a stop means functions to stop operation of the inverter 5. When a timer stops and the output thereof is inverted, pulses for forcibly extinguishing a pulse generating circuit are produced while an ON signal is fed to the inverter 5 thus driving the inverter 5. By such arrangement, voltage compensation can be carried out reliably upon occurrence of instantaneous voltage drop.

Title: Optical information carrier
Inventor: NISHII KANJI
IPC: G11B7/085
Filed: 1984-04-27
Abstract: PURPOSE:To execute a stable track retrieval even when a light spot crosses a guide track at a high speed by placing an area which does not have a guide track substantially, between groove-shaped guide tracks. CONSTITUTION:In flat parts 2-a-2-i, a diffraction phenomenon at the edge is not generated, therefore, with regard to both an output waveform 10a and 10b of an inside periphery side photodetector 4a and an outside periphery side photodetector 4b, the outputs are flat and also equal. Accordingly, a difference signal 11 becomes ''0'' level and a sum signal 12 becomes a flat waveform of a constant level. Accordingly, by detecting a fact that the sum signal 12 exceeds a constant level L and also the difference signal 11 is ''0'' level, it can be detected that a light spot has crossed the areas 2-a-2-i having no guide track substantially. In this way, by placing the area having no guide track, it is possible to obtain an information carrier which can execute a stable track retrieval even when the light spot crosses the guide track at a high speed.

Abstract: PURPOSE:To manufacture an easy-to-use device by providing a cooking equipment with a detection means of a condition of a cooking material and controlling a heating equipment by a supersonic signal. CONSTITUTION:When a container 1 containing water 2 is put on a sheet 12 to start heating by conduction, initially temperature of a thermistor 3 is low so that a control means 4 judges to be 'under heating' and outputs an H-signal to a modulation circuit 5. The circuit 5 impresses high frequency on a supersonic oscillator 6 to generate an ultrasonic wave.

The circuit 8 outputs the H-signal to a driving means 9. The means 9 drives a high frequency current generation means 10 to excite a heating coil 11. As a result, the container 1 is heated so that the control means 4 judges through the thermistor 3 the water 2 inside the container 1 to be 'boiled' so as to output an L-signal to a circuit 5, the circuit 5 impresses the ultrasonic wave to the oscillator 6 to generate the ultrasonic wave, the receiving element 7 receives it to output it to the demodulation circuit 8, the circuit 8 outputs the L-signal to the driving circuit 9 to stop the driving signal to the high frequency generation means 10 and to stop excitation of the heating coil.

Abstract: PURPOSE:To determine the titled isozyme with a good accuracy without an influence of interfering substances, by measuring activity of alpha-amylase using maltooligosaccharide having p-aminophenyl groups at reducing terminals as a substrate in the presence of an inhibiting substance for a specific isozyme. CONSTITUTION:alpha-Amylase isozyme in a sample, such as blood or urine, is fractionally measured. In the process, an inhibitory substance capable of specifically inhibiting a specific isozyme and maltooligosaccharide having p- aminophenyl groups linked to reducing terminals are used as a substrate to measure p-aminophenol liberated by enzymic reaction by a conventional method. Thereby the alpha-amylase isozyme is fractionally determined. Furthermore, a monoclonal antibody, etc., specifically recognizing respective isozymes are preferably used as the substance capable of specifically inhibiting the specific isozyme.
